The Pawns are the soul of the game
The pawn is the soul of chess.
Pawns: they are the soul of this game, they alone form the attack and defense
It is always advantageous to exchange your king's bishop pawn for the king's pawn, since this leads to the seizure of the centre and, in addition, to the opening of a file for the rook.
A pawn, when separated from his fellows, will seldom or never make a fortune.
